Resumo: Este trabalho apresenta a nova versão do aplicativo de apoio ao ensino de Geometria Descritiva para a modelagem de sólidos, o HyperCAL 3D 2. O grupo de pesquisa Virtual Design (ViD) da Universidade Federal do Rio Grande do Sul (UFRGS) desenvolveu uma nova metodologia de ensino para a Geometria Descritiva seguindo a abordagem da aprendizagem baseada em projetos (TEIXEIRA et al., 2006), o uso de objetos sólidos, uma nova nomenclatura e o uso de ferramentas de computação gráfica para auxiliar o processo de aprendizagem. Os principais objetivos são: reduzir o grau da abstração necessário para aprender os conceitos básicos; aproveitar os conhecimentos prévios dos estudantes; garantir o entendimento dos processos bidimensionais e os seus correspondentes tridimensionais e estimular o processo de aprendizagem a partir de problemas concretos com aplicações práticas. Um dos pilares que sustenta esta metodologia é um aplicativo gráfico, o HyperCAL 3D (TEIXEIRA et al., 2007), o qual teve sua primeira versão em 2006 e era baseado na linguagem VRML (AMES et al., 1997) e utilizava um plug-in para a visualização das geometrias. Apesar de limitar as interações, o uso desta tecnologia permitiu um rápido desenvolvimento da versão 1.0, o que garantiu a sua disponibilização a tempo de ser utilizada no segundo semestre de 2006, quando a nova metodologia foi implementada nas turmas de Geometria Descritiva do então novo curso de Design da UFRGS. A experiência com o uso do HyperCAL 3D 1.0 possibilitou avaliar o seu desempenho frente às necessidades do ensino da Geometria Descritiva e, assim, verificar suas qualidades e fraquezas. A partir deste conhecimento foi possível desenvolver uma nova versão, o HyperCAL 3D 2.0 com várias melhorias, tanto na sua interface que utiliza a tecnologia OpenGL, quanto em termos de recursos, como a possibilidade de imprimir os modelos. Este trabalho apresenta esta nova versão desta importante ferramenta de apoio ao ensino da Geometria Descritiva.

Este trabalho apresenta um modelador 3D utilizado como ferramenta de ensino-aprendizagem de geometria descritiva através do paradigma do design-based learning. O HyperCAL 3D foi desenvolvido para que os alunos possam representar em 3D os projetos elaborados a partir dos conceitos de geometria descritiva e, assim, estabelecer relações entre as representações convencionais e a geometria dos objetos em três dimensões. O programa foi implementado em linguagem Delphi e utiliza a realidade virtual, através da linguagem VRML, para visualização dos objetos gerados. A utilização desta ferramenta inovadora tem permitido um salto de qualidade na aprendizagem da geometria descritiva como pode ser visto nos exemplos de projetos desenvolvidos pelos alunos.

This work presents the HyperCAL3D, an application to support the teaching and learning process of Descriptive Geometry through the study of solid objects. The methodology used for its implementation and the main features of the application are described. A selection of concepts was carried out to determine the functional structure of the software should have. From this, the main features were modeled through processes of vector geometry equivalent to that used in Descriptive Geometry. The main features introduced include: the projection process, the representation of hidden lines in three-dimensional model and the projections, successive auxiliary views in real time, and the intersection process. All these tools are implemented in an application that aids the learning process of the students and the teaching procedures of professors.

This article presents the HyperCAL3D applications in Descriptive Geometry education (DG). First, the main features of this application are briefly presented, relating to the conceptual, methodological and technological base used in its development, including the vector modelling of the DG operations and the context of project-based learning. In the second part, the HyperCAL3D is used to perform various applications in typical problems of DG in its educational context, such as auxiliary views; determination of true length of straight, normal view of planes and angles between planes; obtaining axonometric views; obtaining main views. All these applications demonstrate the great potential of HyperCAL3D use as a teaching tool for DG.

This work reports the experience in the implementation of a new paradigm in teaching of descriptive geometry: the Design-based learning. This paradigm changing is the result of a new approach centered on the student, seeking to develop its creativity and its own problem solving capacity based on the descriptive geometry concepts. In this sense, all the concepts and projects developed implicate working with solids. Therefore, it implies in the increasing of the concrete experience, reducing the usual abstraction level needed to learn the fundamental concepts. The proposed methodology was first implemented in some sample classes of Engineering and Design courses of the Federal University of Rio Grande do Sul (UFRGS) with great success.

The Inspaedia moto is to inspire a collaborative intelligence network on innovation and design processes. This paper is focused on Inspaedia user centered design features. We will describe how users can access the web platform, add, explore, relate, and share the Inspaedia contents. It will be a unique, memorable and inspiring collaborative knowledge experience that will facilitate several creative activities. Inspaedia is the natural consequence and development of the prototype resulting from the research in Design PhD thesis entitled " Innovation, design et cetera ". Therefore, the new platform is being developed under the post-doctoral Design in FA/UL – Faculty of Architecture of the University of Lisbon (Portugal); Science Without Borders Program with a Special Visiting Researcher fellowship from CAPES (Brazil) at the PGDesign UFRGS – Federal University of Rio Grande do Sul; CITAD – Research Centre for Territory, Architecture and Design of Lusíada Universities (Portugal); FCT – Foundation for Science and Technology (Portugal). The aim of this paper is to disclose the new research developments and the results from the systematization of experience and user's interaction on the Inspaedia platform. We want to share and discuss the interim results achieved so far with the participants of the 6th AHFE through a visual based presentation of the Inspaedia. We will choose the best outputs to be included in the next phases of the Inspaedia research project.
